Key techniques of transplanting Myrica rubra trees

Myrica rubra is an important ecological and economic forest in China's subtropical zone, which is delicious and evergreen all the year round and very attractive. In recent years, Myrica rubra has been the first choice for landscaping in landscape engineering departments. It has the advantages of fast formation, less infection, easy management and high ornamental value. It is also designated as ecological greening and ornamental tree species by many forest parks. In addition, it is of great practical significance to simply cut down a certain number of trees in Myrica rubra garden to promote the growth of Myrica rubra trees and improve the yield and quality. The key techniques of Myrica rubra transplantation are briefly described for reference.

1. The transplanting period is generally spring sowing, and the suitable period from February to March before germination is also postponed to early April. The planting time should be when it is cloudy or rainy and there is northwest wind in Mao Mao.

2. Dig a pit for planting. Before transplanting, dig a planting pit (diameter: 1 ~ 2m, depth: 1m) and fill it with a small amount of pebbles and red soil or yellow loam with a thickness of at least 0.5m. ..

3. Dig a big tree. Because there is a certain balance between the growth of underground roots and branches above ground, when digging trees, the upper part of the crown should be cut off first, and at the same time, according to the growth of the crown, long branches should be cut short to control the height of the crown (generally within 2-3 meters), which is convenient for transportation and reduces the consumption of water and nutrients. When digging, you should open an annular ditch and use bowl-shaped soil balls, the diameter of which is 6-8 times thicker than the trunk 30 cm from the ground. When digging, the root system must be trimmed and cut in time.

4. Planting techniques: Myrica rubra should be planted as deep as possible. Trees with soil balls should be put in holes first, then the trunk should be righted, and then the soil should be cultivated. The height of the mountain soil should be slightly lower than the soil ball to make the soil fully wet, and then the height of the dry loose soil should be slightly higher than the hole plane. For crown planting, water should be sprayed in stages to fully moisten the leaves, and then the trunk should be covered with straw bales and nylon film to keep the roots moist. There are only 65,438+0/3 leaves left in the crown.

5. The management of transplanting a few days before planting should insist on spraying water on crown leaves 1 time at 8-9 am and 5-6 pm every day. In high temperature season, we should pay attention to check the dryness and wetness of the straw bag at the root, and also fill (spray) water in time.
